Chainway CM2000-1 is a single channel UHF RFID reader module with high performance. It can be integrated in mobile UHF RFID readers, fixed UHF RFID readers, UHF card readers, integrated RFID readers and etc. With high integration level, this reliable module is small in size, low in power consumption. It is also resistant to electromagnetic interference and good at heat dispersion. All make it to absolutely satisfy needs of all environments. The module appeals to challenging industries like warehousing, logistics, apparel, production lines and such.

Industry-leading RF Chip

It employs iminj Indy R2000 UHF RFID RF chip, enabling unprecedented experience of UHF RFID reading and writing with high precision, wide angle and low-phase noise.

Excellent Reading Performance

It reads tags with high stability and receiving sensitivity even under harsh environment. The reading range is over 10 meters when using the 4dBi antenna, and reading rate to be over 200 tags per sec. The self-developed anti-collision algorithm makes it ideal in applications with numerous tags.

Superior Heat Dispersion Capacity

The internal heat sink made of heat sensitive material delivers high heat conduction rate, great heat dispersion capacity, and large contact surface design, thus the module doesn´t need to connect any external cooling devices.Multi-board temperature sensor is adopted and temperature protection can be set to sustain long-term continuous full load working at room temperature.

Strong Stability and Monitoring System

You can expect reliability when deploying it under temperature -25°C to 65°C, and humidity 10% to 95%. It can work continuously for 24 hours x 365 days without crash and is resistant to electromagnetic interference. It detects antenna connection, protects RF receiver and can be cancelled by command. Integrated RF chip even makes it more stable, making it better to stand up to harsh environments.

Low Power Consumption

It operates perfectly well under DC 3.5V power input. It is born with low power consumption, to be 5.3W, 0.15W and 1μW under RF output mode, standby and power off mode respectively, which significantly extends the service time of UHF devices.

Outstanding Consistency

It adopts high-precision and reliable components and parts to ensure high consistency. It is definitely a masterpiece of consistency.

Easy Application Development

SDK and developing board are available to facilitate a secondary development. You are allowed to connect the PC to test it, making the whole process more convenient and efficient.
